96 LT1...

Drove the car to the store, ran fine... Came out and now all it wants to do is crank and attempt to start. Just a real quick fire and nothing. I'm thinking it's a fuel problem. Just want to get some more suggestions before starting there.

It does have a secondary fuel pump due to a PD supercharger so the pod gauge is reading about 47 psi. with the ignition on.

Any input will be greatly appreciated...

Thanks
